What is
Arthrosamid?

Described as the ‘liquid knee replacement’, Arthrosamid offers long-lasting relief for knee osteoarthritis.

Depending on the main driver of your knee condition a high proportion of the discomfort and pain from your arthritis could be coming from inflammation of the knee joint capsule and the fluid produced, not just joint wear.

Arthrosamid® is a revolutionary hydrogel treatment designed to reduce or stop inflammation which addresses this pain source and delays wear. This is as inflammation can degrade a joint directly or indirectly through loss of strength and therefore stability. 

Its unique composition ensures it remains effective long-term, providing lasting relief from joint discomfort in a single injection. Dubbed by one patient the ‘liquid knee replacement’ due to its longevity with current research showing 5 years (limited only by the length of the trial so far) and recipients having lasted much longer.

Rediscover a pain-free, active lifestyle with Arthrosamid®.

What to expect

A Non-Biodegradable Hydrogel for Lasting Comfort

Injection Process

The injection is precisely administered into the knee joint using ultrasound guidance for maximum accuracy, ensuring the hydrogel is delivered to the exact spot so it can find its home in the capsule of the knee.

Alleviates Pain

Arthrosamid® is absorbed into the capsule where, as non-biodegradable, it remains to blocks inflammation from occuring. This results in pain relief, ablity to use the knee and stay strong and thus delay wear. Unlike temporary treatments, the hydrogel stays in the joint to provide consistent relief for years.

Long-Term Results

The hydrogel’s non-degradable properties mean it provides sustained benefits. Most patients begin to feel relief within weeks, and the effects can lasts 4 or more years, offering significant pain reduction and improved joint function over time.

Injection Process

Personalized Care for Optimal Results

Arthritis can be driven in a number of ways i.e. trauma, or a bias towards either  bone degradation or inflammation of the joint. Each knee will be driven differently and at a different stage of wear.

Every patient is different with regards to such factors as to stage of life to have a replacement, ability to have a replacement, finances and applicability for the injection.

Having attended a user group meeting in Denmark at the Contura factory, having completed the procedure over 20 times and with the ability to review the knee on ultrasound Mark is an expert in patient selection and this consultation is crucial to help you consider what result you could expect from the injection. 

Prophylactic antibiotics are required to be taken 1-2 hours prior to your injection. Your current symptoms and mobility levels will be recorded, if not already. The procedure itself takes approximately 30 minutes per knee and is performed under ultrasound guidance for accuracy and help draining the knee if required. A single needle is used to administer local anesthetic and 6ml of Arthrosamid.

 Your knee might feel ‘tight , cushioned, full, a bit pressured’. The local anaesthetics will last for approx three hours so you will be pain free. Details of a knee rehab programme are discussed. it is recommend someone else drive you home however most patients are self sufficient.

After the procedure, you are advised to rest for 72 hours.

What will it feel like after the injection?

The body. takes time to recognise the foreign substance is not a threat and and to absorb / accept the hydrogel – So for the first 6 weeks you may experience some pain/more pain and discomfort.

This is due to:

Post injection flare: Injection-related mild to moderate pain and/or mild swelling during the first few days to weeks following the injection may occur or increased swelling of Baker’s cyst present may also occur

When will I begin to feel less pain?
It can take four to twelve weeks to feel the maximum benefit. Clinical data
shows that most patients start to feel an effect within a few weeks.

Early responder = 1-6 Weeks
Typical Responder = 6-12 weeks
Delayed Responder = 3M – 6M

Not all patients respond at the same rate and achieve the same reduction in pain

When can I go back to normal activity?

48H reduce activity/rest
First 2 weeks normal ADLs;

As with any invasive joint procedure, it is recommended to avoid strenuous activity (e.g. tennis, jogging or long walks) during the first few weeks after the injection and begin rehabilitation activities when possible.

Our team is always available to address your concerns and guide you through your recovery journey.

For any unforeseen circumstances and safety it is recommend someone else drive you home however most patients are self sufficient.

Why Use Point-of-Care Ultrasound (POCUS)?

Improved Accuracy and Outcomes for Joint Injections

To ensure the most precise and effective treatment, we use Point-of-Care Ultrasound (POCUS). This advanced diagnostic tool helps guide injections to the correct location within the joint, optimizing accuracy and improving results.

Precision in Small Spaces

Joints like the shoulder bursae or hip require precision to ensure the injection hits the target. Ultrasound ensures the needle is accurately placed.

Deep Tissue Access

Some joints and tendons, such as the hip joint or hamstring tendon, are too deep to reach without guidance.

Accurate Diagnosis

POCUS helps to distinguish between conditions like Achilles tendinopathy and retrocalcaneal bursitis, ensuring the correct treatment is provided.

Using POCUS enhances the effectiveness of your treatment, allowing for better outcomes and a more comfortable experience.

Frequently Asked Questions

Arthrosamid is an innovative, non-biodegradable hydrogel injection designed to provide long-lasting pain relief for knee osteoarthritis. It works by integrating into the synovial tissue, reducing inflammation in the joint helping it to be as pain free as possible and stay strong and stable delaying wear.

The gel absorbs into the joint capsule and the magic bit is the make up of the gel is similar to the bodies cells in that area so the body doesn’t reject, allows it to sit one cell layer deep, and being non-biodegradable it stays there. 

It then helps return the thickness and regularity to the knee capsule lining and prevents inflammatory cells communicating all of this leads to less inflammation in the joint. This helps to restore mobility and provide significant, long-lasting pain relief for osteoarthritis sufferers.

Clinical studies have demonstrated that Arthrosamid provides substantial pain reduction and improved knee function for osteoarthritis patients. Unlike steroid injections, which offer temporary relief, Arthrosamid is designed to provide long-term benefits with fewer side effects.

Arthrosamid is ideal for individuals with inflammatory led knee osteoarthritis who are looking for long-term pain relief without surgery. There are many factors that will determine your suitability such as your age, grade of arthritis, applicability to surgery. Mark at Rebound physio has been part of user group meetings in Denmark at the Contura factory and is a specialist in patient selection and can guide you as to how you might benefit. 

Arthrosamid injections are provided by specialists in musculoskeletal medicine. You will typically require an initial assessment to determine your suitability before receiving the injection at a clinic offering ultrasound-guided procedures.

Most patients experience little to no downtime after the injection. You may feel slight discomfort for a few days, but normal activities can typically be resumed shortly. Full pain relief benefits are often noticeable within weeks.

Arthrosamid is well-tolerated, but some patients may experience mild swelling, stiffness, or temporary discomfort at the injection site. Serious side effects are rare, and no allergic reactions have been recorded.

  • Steroid injections: Provide temporary relief but do not improve joint structure.
  • Hyaluronic acid injections: Offer lubrication and are more joint surface based but have shorter-lasting effects.
  • Arthrosamid: Integrates into the joint lining, providing long-term pain relief with a single injection.

Studies suggest that a single Arthrosamid injection can provide pain relief for up to 5 years, making it one of the longest-lasting injectable treatments for knee osteoarthritis.

Patients can slowly resume their normal low impact daily activities approximately 72 hours post injection.

However with any invasive joint procedure, it is recommended to avoid strenuous activity (e.g. tennis, jogging or long walks) during the first few weeks after the injection and begin rehabilitation activities when possible.
